WPA Cracker is a WiFi security compromiser in the cloud, running on a high-performance cluster. Send them a dump of captured network traffic and $35, and they will try 136 million passwords in 40 minutes, tops (for $17, they’ll run the same attack at half speed) — the same crack would take five days on a “contemporary desktop PC.” They also have an extended, 284 million word dictionary that you can run for $55 in 40 minutes. They’ll also use the same process to crack the passwords on encrypted ZIP archives.
